Story
The brooch is consistent with 20th-century decorative silver jewelry, but its workshop and ownership history are unknown. The photographed secondary mark is compatible with '19 GE'; a workshop number paired with GE is consistent with registration in Genoa, Italy, pending confirmation against a reliable hallmark record. Neither that provisional origin nor the 900 stamp establishes a named-maker premium or a narrower date.
Maker / Origin
Unattributed
Condition & Value
The photographs show largely intact blue enamel, applied wire strings and an openwork filigree reverse, with substantial multicolored tarnish. No obvious major structural damage or solder repair is apparent, although dark areas and surface irregularities cannot confidently be separated from decoration or minor wear.

Market Analysis
Small musical-instrument brooches appeal to vintage-jewelry collectors, musicians and gift buyers on eBay and Etsy. The supplied evidence shows modest resale prices, with decorative enamel and filigree offering more differentiation than silver content alone. Unattributed examples compete primarily on appearance, condition and presentation rather than workshop history. The available records are too sparse to establish a current price trend or reliable sell-through rate.
Value Drivers
▲ Blue enamel and dimensional guitar detailing provide decorative appeal beyond metal value.
▲ Twisted-wire strings and openwork filigree distinguish it from simpler instrument pins.
▲ Visible 900 stamp and owner-reported acid test support a probable silver body.
▲ Wearable 38-by-16-mm size and reportedly secure clasp support individual resale.
Concerns
▼ Dark enamel areas remain ambiguous; confirmed chips or restoration could reduce value.
▼ Exact bulk fineness and fitting alloys are unverified; gross weight overstates silver-only weight.
▼ Photographs cannot exclude small solder repairs or weaknesses in the delicate wirework.
▼ Few verified priced comparisons make the upper end less certain.
Best Venue
List individually on eBay at approximately $95 with offers enabled; a negotiated sale around $60–$75 would fit the central estimate, while $40–$50 is a practical faster-sale target. Include sharp front, reverse and hallmark photographs, dimensions and gross weight, and describe the origin as provisionally Italian rather than definitively Genoese. Avoid abrasive polishing or chemical dips that could affect the enamel or filigree, and pursue workshop research only if a reliable hallmark record is readily available.
Upside Potential
Excellent enamel condition confirmed in close-up and strong presentation could support a sale near $90, comparable to the USD 90. 95 guitar listing, though that transaction remains unverified. Exceeding the range would require a documented collectible maker attribution and supporting sales, not simply confirmation of Italian origin.
